Specification of Letters Patent.

Application filed February 14, 1914. Serial 0. 818,797.

Be it known that I, HERBERT E. WILLIAM- SON, a citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented new and useful Improvements inGearing, of which the following is a specification.

The object of the present invention is to provide a steam washingmachine for domestic use which will be simple of construc: tion, and oflow cost, capable of being operated by a small motor, which will beunder the complete control of the user and which will be very effectivein its operation.

In the accompanying drawing, Figure 1 is a perspective vlew of themachine; Fig. 2 is an enlarged broken vertical section thereof; Fig. 3is a broken inside view of one end of the tank; Fig. 4 is an enlargedbroken vertical section of the machine; Fig. 5 is a sectional view,showing in elevation the inner side of the other end of the tank; Fig. 6is a side view of acam; Fig. 7 is a side View, and Fig. 8 an edge view,of a rotator'ring.

Referring to the drawing, 1 indicates a rectangular hollow box-likebody, closed at thetop by a removable cover 2, and open at the bottomand supported upon legs 3, adapted to travel upon casters 4. Within saidbody, but depending below its bottom, is a -iosed iron tank 6, which isdrained by a pipe 7 closed by a valve 11, loosely hinged at the top, asshown at 9, and having on its outer side a rib 8 which is adapted to beengaged by the middle portion of a yoke 12 to press the valve down toits seat, said yoke being raised by a r0d13, the upper portion of whichextends through a guide 14 upon an end .of the body. When saidrod is soraised the yoke abuts against a lug 16 projecting from the valve, andraises the valve from itsseat. i

To the under side of the tank is secured an eye 17 adapted to be engagedby a hook 18 upon an end of a gas burner tube 19, the other end of whichis adapted to be connected to a flexible tube, not shown, leading to agas supply pipe. Said other end has a hook 22 secured upon the adjacentend'of the tank and removably' held in place by a pin 23.

Within the tank is a clothes' cylinder 24, i

- rotating in 21 which extends upwardly through an eyewhich they can beraised from their keepers."

On one end of the cylinder is secured a gear wheel 36 and from said gearwheel and fromthe other end of the cylinder extend centrally trunnions37. The trunnion on said other end is adapted to rest in a bearing 38secured on the inner surface of the corresponding end of the tank, andopen at the top, so that the cylinder can be raised therefrom, while theother trunnion is guided by jaws 39 secured to the other end of the tankand converging downwardly toward a fixed support 41 on said inner end.Between said support and jaws can move the ends of fingers of abifurcated lever 42, pivoted on the inner side of the corresponding endof the tank, of which one end is connected to an end of a link 47, theother end of which is connected to the free end ofa crank arm 43 on ashaft 46 passing through the adjacent end of the tank and body, andhaving on the outer end a hand lever 44 by which it can be turned. Byturning this hand lever the adjacent trunnion of the cyl- A lnder can bemoved horizontally to the right or left as desired.

When moved in one direction the gear ,wheel 36 on said cylinder is inmesh with side of saidigroove 1s a cone 56 on a shaft 57 said bracketand having secured thereon a pulley 59 with a deep groove 61.' In saidgroove is a belt 62 extending from the shaft of a motor 63 secured upona leg of the machine. By means of said motor, and by the frictionalengagement of said cone 56 with said wheel 53, the cylinder is rotatedwithin the tank, and the Water in the tank is there by caused to passthrough the clothes in the cylinder and wash the same. -However, Iprovide means whereby, mined number of rotations in either direcabearing 58 supported upon after a 'predeter- Hence, with a rocking levercylinder,

' of the Shifter.

lows:To the gear wheel 36 is secured a pin 64:,"Whi0h, once in eachrotation of the is adapted to engage an arm 66 of a number, here shownas three,of arms on a shaft 67 rotating in a tube 68 extending throughthe adjacent ends .of the tank andbody.

Secured to the shaft 67,-within said tube' 68, is a ring 69, from theperiphery of which extends outwardly, in a direction parallel with theshaft 67, a lug 71, two similar rings 72 loose on the shaft'havingsimilarly extending lugs 73, the last lug 73 extending in a groove 74 inadisk 76 loose onthe shaft. The peri hery of said disk is formed atopposite si es with cam surfaces 77, (Fig. 6) which engage the ends ofarms 78 extending from .a shifter 79 pivoted at the bottom, as

shown at-81, to the bracket 52, sothat, as the disk is turned, saidshifter is rocked. In said shifter is a loose bearing 82 for the shaft57 of the friction cone, and springs 83 onopposite sides-of the bearing82 are comressed between said bearing'and the ends rocked, the frictioncone moves out of contact vwith one side of the groove in the wheel 53and-into contact with the other side of said groove, and, the'shaft 57being rotated from the motor constantly in one direction only the motionof the shifter causes the grooved'wheel 53 to be rotated in the oppositedirection to its previous direction. each nine rotations of the clothescylinder, the direction of its rotation is reversed automatically. For,with each rotation, the pin 64: rotates the shaft 67 through one-thirdof a rotation and with ',one rotation of the shaft, the lug 71 of thefirst ring engages the lug 7 3 of the second ring and causes it torevolve with it, so that in three rotations ofthe shaft 67 or nine ro--tations of the cylinder the last lug 7 3 reaches the end of the groove74 causing the disk 76 to. rotate and actuating the shifter 79. It maybe reversed voluntarily by moving 84 pivoted on the body and pivoted toa link 86 the other end of which is" pivoted to said disk. Or the motionof the clothes cylinder can be brought to .rest bymoving said rockinglever 84 to a central position, thereby causing the shifter to assuine acentral position, so that the friction cone makes a driving contact withneither wall of the groove of thewheel 53.

, On the ing notches 88 in its'side, which can be engaged by pinsS9'extending outwardly from the adjacent hub of the grooved wheel 53.Said sleeve is moved longitudinally. along 1 said shaft 51 by forksextending from the 6' lower end of a lever When the shifter is thusactuated by said shaft 51 is a loose sleeve 87, havjacent end of thebody 1. When the upper end of .said lever is moved toward said body,'thelower end is moved toward said wheel 53-, and said lugs are caused toengage the sleeve 87, imparting rotation thereto from the rotation ofthe shaft 51. On said sleei e is a sprocket wheel 94 whichis engage-dbya sprocket chain 96 which alsoengages a sprocket Wheel 97. on theshaft 99 ,of.

' the lever 14.

To use the wringer a lever 91 is actuated to cause the, sleeve 87 torotate with the shaft 51.

I claim I 1. The combination of a shaft, an element rotated thereby, anextension from said element, a gear wheel secured to said element,
